ENERGY TRANSFERS IN THREE-FREQUENCY CIRCUITS WITH MAGNETIC COUPLING

摘要

The energy transfers in three-frequency circuits coupled through a nonlinear magnetic core are studied. Rules are given to determine the type of nonlinear characteristic needed to make energy transfers possible for given frequency combinations. General energy relations of the Manley Rowe type are discussed, examining the validity and Limitations of these relations for the practical case where the frequency ratios are not irrational. Examples of the use of the analysis are given for oscillators, sub ringers and amplifiers with a variety of frequency ratios.
